We are happy to announce our latest research published in Photonics. This study focuses on the statistical modeling of Digital to Analog Converters (#DAC) within optical transmission systems. Our work, within the FLEX-SCALE project, provides closed-form analytic expressions for key DAC performance metrics, which are crucial for understanding the behavior of optical systems with coherent detection. 𝗥𝗲𝘀𝗲𝗮𝗿𝗰𝗵 𝗛𝗶𝗴𝗵𝗹𝗶𝗴𝗵𝘁𝘀: 👉 𝗔𝗱𝗱𝗿𝗲𝘀𝘀𝗶𝗻𝗴 𝗖𝗵𝗮𝗹𝗹𝗲𝗻𝗴𝗲𝘀: We explore the impact of random current mismatch in DAC drivers, a significant factor affecting system performance. 👉 𝗜𝗻𝗻𝗼𝘃𝗮𝘁𝗶𝘃𝗲 𝗠𝗲𝘁𝗿𝗶𝗰𝘀: Traditional #INL / #DNL metrics are re-evaluated, leading to the introduction of the "integral error vector" (#IEV) and "differential error vector" (#DEV) metrics. These new metrics offer better predictions for communication system performance. 👉 𝗣𝗿𝗮𝗰𝘁𝗶𝗰𝗮𝗹 𝗜𝗺𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀: The study links these metrics to practical outcomes like error vector magnitude (#EVM) and error rates, providing valuable insights for telecommunications systems design. This research marks an important advancement in improving the performance and reliability of optical transmission systems.
